Experimental Study on Organic Sulfur Removal in Bituminous Coal by a 1-Carboxymethyl-3-methyl Imidazolium Bisulfate Ionic Liquid and Hydrogen Peroxide Solution.

ABSTRACT: In order to improve the total sulfur removal rate in coal combustion, an acidic ionic liquid (IL) 1-carboxymethyl-3-methylimidazolium hydrogen sulfate ([HOOCCH₂mim][HSO₄]) as the extractant combined with the oxidant 30% hydrogen peroxide (H₂O₂) was applied to reduce the total sulfur content, and its microscopic mechanism of desulfurization was analyzed. The experimental results show that the desulfurization rate of the [HOOCCH₂mim][HSO₄]-H₂O₂ (1:10) solution was 45.12% and the organic sulfur removal rate was 16.26%, which were significantly higher than those of only H₂O₂ or pure [HOOCCH₂mim][HSO₄].
